For some time we have had our public support site with GetSatisfaction. As of immediately we have switched to our own support forums over at http://forums.razuna.org. All links within Razuna have been changed with the final 1.6 release.
The new forums allows us to set up dedicated forums for some of our customers, plus we feel that an open forum is much better suited to our needs. That said, please post any questions to http://forums.razuna.org from now on.
